inch valve: The patented design miniature fluid pump imparts an exceptionally durable syringe valve, non-sticking pinch valve with no-clog flow path for handling solenoid valve aggressive, particulate-laden liquids. For moderate miniature liquid pumps chemical inertness and waste lines where particles may be present.

miniature check valves:Bio-Chek™ from biochem valve In-line check valves provide a gentle, economical miniature solenoid valve, non-metallic flow path for handling low volume plastic solenoid valves, low flow transfers inert valve without causing backflow or miniature check valve turbulence.

column chromatography liquid - The need for a fully inert fluid path in preparative column chromatography HPLC instruments is satisfied with our line of isolation and mixing valves. These miniature fitting miniature valves provide all-Teflon flow paths, small footprints, and accuracies required of this demanding application. Examples of our valves used in HPLC instruments include a 2-way inert solenoid valve used to act as an off/on miniature fitting waste valve and as a pressure relief to protect an analysis cell.

Medical Instrumentation laboratory glass bottles - Miniature solenoid valves are used in a wide range of medical instrumentation including dialysis machines and automated slide staining equipment. Specific applications for miniature plastic tube fittings valves include saline wash maintenance for surgery, pinching tubing used in disposable patient kits, and pumping solution away from the areas of patient contact. The plastic compression fittings adaptability of our standard product line allows our valves teflon tubing and fittings to be used in many 'non-standard', high-purity or chemically aggressive applications as well.

Environmental Analysis plastic barb fittings - The ability to measure and track our surroundings is critical in today's world. Our rotary valves are specified in instruments that measure air and water composition throughout the world rotary direction control valve. Air sampling equipment uses pinch valves to create a vacuum for drawing in air at specific intervals. Particle counters fluidic components, daily environmental monitoring units, and marine biology instrumentation also utilize our solenoid valve technology to achieve accurate measurements.

Products
Large electrical rotary valves
Omnifit's large electrical rotary valves are designed for use with aggressive chemicals or biologically sensitive materials.
Small electrical rotary valves
Omnifit's small electrical rotary valves are designed for use with aggressive chemicals or biologically sensitive materials and have an inert, Teflon® body and Kel-F® rotor. Pressure rated to 500 psi (33 bar). Minimal dead volume, bulkhead mountable. 12VDC, 4 watts. Includes control board with control signals for clockwise drive, counter clockwise drive, 'HOME' flag and 'MOTOR ACTIVE' flag. Bore size is 1.5mm, step time is 200 milliseconds.
Small high pressure manual rotary valves with 1/4 - 28 UNF helicoil connections
These manual rotary valves are constructed from PTFE with a 0.8mm bore size, making them suitable for high pressure applications up to 500 psi (33 bar). They are available in 4 and 5 port versions and any spare ports can be sealed with a plug (part number 2320) for maximum flexibility. All ports are 1/4"-28 UNF flat-bottom and will accept any 1/4"-28 UNF male fitting. Omnifit's 1000 psi pressure rated Gripper fittings are ideal for use with these valves. Valves are bulkhead mountable (mountable onto any flat surface) with pre-drilled holes for easy mounting.
Small manual rotary valves with Omnifit 'cap-type' connections
Omnifit's small manual rotary valves use the 'cap-type' connection system and can be used for sampling, flow-splitting, mixing and fluid line interconnection. They have a 1.5mm bore size and accept tubing sizes between 0.5 and 4mm OD. They are pressure rated to 50 psi (3.3 bar). The body is PTFE and the key is Kel-F®. The valves are available in 4 and 5 port versions and any spare ports can be sealed with a plug (part number 2320) or by using a PTFE cone blank (part number 1514) for maximum flexibility.
